Exam 1
Simplest to most complex from atom to organs
What is: atom, molecule, cells, tissues, organs
Cells that store fat
Adipocytes
Attaches muscle to bone
Tendon
three meninges from neural tissue to bone
pia mater, arachnoid mater, and dura mater.
Anatomy is to structure as physiology is to
function
The chemical behavior of an atom is determined by this.
Outermost electron shell.
This layer is only found in thick skin
Stratum Lucidum
Slightly moveable joint
Amphiarthroses
Sorts, relays information
Thalamus
Sister chromatids are pulled apart to opposite ends of the cell.
What is Anaphase?
This feedback enhances a stimulus
What is positive feedback?
If you are exposed to abundance of sunlight, you would have more of this to protect your skin from damage.
What is melanin?
decreases the level of calcium ion in the blood.
Calcitonin
This cranial nerve controls ANS functions
Vagus nerve.
Changes shape of lens
What is ciliary body
The process of forming mRNA
What is transcription?
This epithelium is found in the inner lining of the mouth
Stratified squamous
Steps of muscle contraction
1. power stroke
2. Relaxation and unbinding
3. Cross Bridge
4. Action potential
3. Cross bridge
1. Power stroke
2. Relaxing and unbinding
High visual acuity is dependent on
cones
Role of tropomyosin
Tropomyosin serves as a contraction inhibitor by blocking the myosin binding sites on the actin molecules
Purines found in DNA
Adenine and Guanine
Tissues that provide strength and support for areas subjected to stresses from many directions
Dense Irregular connective tissue
Place the events that occur at the neuromuscular junction after the action potential reaches the axon terminal the correct order.
3. Ca enters axon terminal
6. Synaptic vesicles release Ach
4. Ach binds to receptors
1. Ligand channels open
2. Sodium enters and potassium exits
5. Membrane potential is less negative.
Steps of light passing through eye
1. Aqueous humor
2. vitreous humor
3. Cornea
4. Lens
5. Retina
1. Aqueous humor
4. Lens
2. Vitreous humor
5. Retina
3 types of fibrous joints
Sutures (skull), gomphoses (teeth/jaw), Syndesmoses (tibial/ligament)
